JavaScript Number Pattern 32

Here`s a program that prints the above number pattern using JavaScript Programming:

example.html

Copied

<!DOCTYPE html>
<html>
<body>

<script>
var i, j, k;
for(i=1; i<=5; i++)
{
 for(j=1; j<=i; j++)
  document.write(9+i+j +" ");
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

When you run the above program, it will print the following output:

Output

11 
12 13 
13 14 15 
14 15 16 17 
15 16 17 18 19

🧠 How the Program Works

Let's break down the logic behind the code:

var i, j, k;: This declares three variables i, j, and k which will be used in the loops.
for(i=1; i<=5; i++): This initiates a loop that runs from i = 1 to i <= 5. In each iteration of this outer loop, the value of i will increase by 1.
Inside the outer loop, there is another loop: for(j=1; j<=i; j++). This initiates a nested loop that runs from j = 1 to j <= i. In each iteration of this inner loop, the value of j will increase by 1. The inner loop is responsible for printing the numbers and spaces on the same line.
document.write(9+i+j +" ");: This line of code writes the value of 9 + i + j followed by a space. The value of i represents the current value of the outer loop variable, and the value of j represents the current value of the inner loop variable. So, for each iteration of the inner loop, it will print 9 + i + j along with a space.
After the inner loop completes, the program writes "<br>". This HTML tag represents a line break, so it will move the next printed output to a new line.
The outer loop continues to iterate, increasing the value of i by 1 in each iteration. As a result, the inner loop runs a varying number of times based on the current value of i, which results in different numbers being printed in each line.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
